Legislatures around the country have working to comply with the new law. Currently, Idaho is the only state in the West where hemp is still illegal.

The Idaho bill is sponsored by Republican Reps. Caroline Nilsson Troy of Genesee and Dorothy Moon of Stanley.

The first part of the measure legalizes hemp in Idaho, and the second removes hemp from the list of Idaho's Schedule 1 controlled substances, so long as it contains 0.3 percent or less of THC, the psychoactive ingredient in marijuana.

The legislation comes as a Colorado company is suing Idaho agencies, trying to get its shipment of 6,700 pounds of declared hemp that Idaho State Police confiscated in January during a traffic stop and arrest.
